Hello everyone, I have a question regarding the UNB and UNT parameters, the models that I have designed is a 40-story steel structures. one model is only beams and columns and the other have core and outriggers at the top. is it important to assign UNB and UNT to carry on the design? I attached pictures as well as the staad files for the models
8540.Model 1.STDModel 3.STD
UNB and UNT are optional parameters. If those are not provided, it will be taken equal to the member length.
